Make all of the RecTy constructors private, and use get() factory
methods instead. Return singleton instances when it makes sense.

ListTy instance pointers are stored in the element RecTy instance.

BitsRecTy instance pointers, one per length, are stored in a static vector.

Also unique DefInit instances. A Record has a unique DefInit which
has a unique RecordRecTy instance.

This saves some 200k-300k RecTy allocations when parsing ARM.td. It
reduces TableGen's heap usage by almost 50%.

Hopefully fix some GCC-based buildbots. GCC apparently decays the array to a pointer here before overload resolution, so construct with an explicit length instead.

Migrate LLVM and Clang to use the new makeArrayRef(...) functions where previously explicit non-default constructors were used.
Mostly mechanical with some manual reformatting.

llvm-svn: 135390

Introduce the 'makeArrayRef(...)' family of functions, which fills a similar role for ArrayRef<> as std::make_pair() fills for std::pair<>: they return the right instantiation of ArrayRef<T> based on the types of the parameters.

They mostly mirror the ArrayRef constructors, with two exceptions:
 * There's no function mirroring the default constructor because it wouldn't have any parameters to deduce the right ArrayRef<T> from.
 * There's an explicit SmallVector<T> overload in addition to the SmallVectorImpl<T> overload. Without it, the single-element overload would try to create an ArrayRef<Smallvector<T> > because it's a better match according to the overloading rules. (And both overloads are used in the current tree, so neither is redundant)

When trying to rematerialize a value before an instruction that has an
early-clobber redefine of the virtual register, make sure to look up the
correct value number.

Early-clobber defs are moved one slot back, so getBaseIndex is needed to
find the used value number.

Bugpoint was unable to reduce the test case for this, see PR10388.

When building LLVM/Clang on Solaris. The generated makefiles would
have an extraneous semi-colon character in them prior to this change
due to the way the 'CMAKE_CXX_FLAGS' variable was defined. Simply
adjusting the definition by moving the current CMAKE_CXX_FLAGS value
within the quotes solves the problem.

Make the disassembler able to disassemble a bunch of instructions with names in the TableGen files containing "64" on x86-32.  This includes a bunch of x87 instructions, like fld, and a bunch of SSSE3 instructions on MMX registers like pshufb.  Part of PR8873.
